USB 2.0 Ethernet 10/100 Network LAN RJ45 Adapter
Let’s start with one of the cheapest USB LAN RH45 Ethernet adapters. This model is available on numerous websites with the cheapest solutions (such as DealExtreme), while it can be recognized easily since it does not have any brand assigned to its name. Simply called USB 2.0 Ethernet 10/100 Network LAN RJ45 Adapter, it starts at $3.22. In order to use it, it is only required to plug it into the USB port and it is ready for use. Everything sounds great – low price, easy installation. Is this really as great as it sounds? I had one – consider the “had" keyword. The main problem with this solution is its construction. After a while, the USB connector starts to detach from the plastic part of the device. Naturally, this results in failure and a device that should be replaced. In order to avoid this, an Ethernet cable should be placed horizontally away from the device, not pushing it towards the desk. Since this is hardly achievable, we cannot recommend this solution.
